COTTON-PRESS;

SPECIFICATION forming part of Letters Patent No. 591,304, dated October 5, 1897. Application filed October 16, 1896. Serial n. 609,148. (No model.)

I To all whom it may concern.-

' vide means to guide the bat of cotton around the. core-roll or around the bale in process of.

formation and .to prevent sagging and breaking of the bat at the under side of the bale.

To this end my invention consists in the use, in combination with the compressionrolls and the core-roll of a cotton-press of this type, of a belt or endless apron, which passes over both of said compression-rolls and beneath the core-roll or the bale while in process of formation.

The invention also consists of the various other features, combinations of features, and details of construction hereinafter described, and then pointed out in the claims.

In the accompanying drawings a cottonpress embodying my invention is fully illustrated. Y 1

Figure 1 is a top plan view of a rotary cotton-press embodying my invention; and Fig. 2 is a side view thereo Referring now to the drawings, A. is the frame of the press; A, the stationary compression-roll; A the movable compressionroll, which is mounted in sliding bearingblocks a, fitted to and longitudinally movable in guides or ways a, formed in the pressframe A; A the core-roll, supported between ing-blocks a fitted to and longitudinally movable in the guides or ways a, in the same manner as the blocks a of the movable compression-roll A and A the pressure-cylinder whereby the'bale in process of formation is subjected to the desired pressure through the medium of rigid connection between a piston fitted thereto and thebearing-blocks a of the movable compression-roll. All of the foregoing parts are old and well known in the art and may be of any desired or approved construction and need not be described in detail."

The means for rotating the compressionrolls A A are also old, comprising a counter-shaft I), mounted in the pressframe A, adjacent to the compression-roll A; a second counter-shaft I), mounted in the bearingblocks Ct, adjacent to the compression-roll A pinions B B, secured to which respectively engage gears B B secured to the shafts of the compression-rolls A A said countershafts b I) being driven in the usual manner, the shaft b from any suitable source of power and the shaft 1) from the shaft 1) by a chain belt B adjusted to sprocket-wheels B 13, secured to the said shafts b b, respectively.

The driving mechanism shown, however, differs from that heretofore used in the respect that both compression-rolls A A are driven through the medium of clutches, thus making provision for disengaging both rolls, so

that said rolls may be driven and stopped A A and beneath the core-roll A or a bale I in process of formation thereon,- said belt or apron being long enough to permit necessary travel of the movable compression-roll in the formation of a bale.

As the'size of a bale in process of formation increases and the movable compressionroll A recedes from the stationary compression-roll A it is obvious that the belt or the compression-rolls A A in sliding bearapron C will be retarded relatively to the surlface of said movable compression-roll, thus 'tional engagement between said belt and movable compression-roll. In practice, however,.I prefer to increase the frictional engagement between said belt and thecompres ployed for this purpose. As shown, they are as follows: Supported above the stationary compression-roll A, in suitable brackets c, secured to the press-frame A, is a roll 0, which bears upon said belt with a light pressure and holds said belt in contact with said stationary roll A with corresponding force. The roll 0' is preferably supported in such manner as to be adjustable toward and from the stationary com pression-roll A. As shown, said roll is supported in bearing bloeks c, fitted to and movable in guides or ways 0 formed in said brackets 0. Threaded into the brackets at the bottoms of the slots 0 are screws 0 upon the heads of which the bearing-blocks 0 rest. The roll 0 is supported against movement away from the compression-roll A by means of screws 0 which bear upon caps 0 between which and the bearing-blocks c are inserted rubber cushions c, which permit said roll C to yield slightly away from said compression-roll A. Obviously when a bat of cotton is passing beneath the roll 0 the belt 0 will be held against the compression-roll A with great force, which will effectually prevent slipping of said belt upon said roll.

Supported in the bight of the belt C be neath the press is a heavy roll 0 the weight of which creates a strong frictional engagement between the belt 0 and the compression-rolls A A independent of other agencies. As shown, axial lugs or projections c on said roll 0 engage guides or ways formed in suitable brackets or standards 0 This construction operates to maintain said roll in proper position and also permits desired movement thereof.

In addition to the foregoing instrumentalities I also prefer to use what may be termed a tension-roll (1 applied to the movable compression-roll A As shown, said roll C is supported in brackets 0 secured to or formed integral with the bearing-blocks a of said movable roll in such position that it will be below the top of the compression-roll A so that it will not interfere with discharging the bale from the press. The roll C is preferably covered with a layer of soft cloth, so that its tendency to cut the belt will be reduced to a minimum.

The operation of my improved press is apparentwithout a detailed description.

I will now describe the method of discharging a bale from my improved press. The bale having attained desired size and having, preferably, been covered, the clutch 13 through which the compression-roll A is driven, is disengaged. Under these conditions operation .of the press by rotating the movable roll A will force the bale upward from between said compression-rolls, and the belt 0, being supported against movement relatively to said compression rolls, will straighten said belt between the tops of said compression-rolls, thus raising the bale into a position from which it may quickly and conveniently be removed, as clearly shown in diagram Fig. 2 of the drawings. The bale having been discharged the belt or apron C may conveniently be depressed between the compression-rolls, so that a core-roll may be placed in the press above the same preparatory to beginning the formation of another bale, in the following manner: The clutch B which drives the compression-roll A, is engaged, and the clutch B which drives the movable compression-roll A is disengaged. The belt C, being held from slipping on the disengaged roll A operation of the press will form a fold in said belt between the compression-rolls, so that a core roll may be placed in position in the press above the same in the manner desired. The tension-roll C will operate to prevent slipping of the belt 0 upon the surface of the compression-roll A In case the tension-roll O is not used slipping of the belt upon the compression-roll A may be prevented by imposing a weight upon said belt where it passes over said compression-roll.

Having replaced the core-roll in the press the movable roll A is returned to its initial position in the baling operation and the belt drawn taut beneath the core-roll. To effect the tightening of the belt beneath the coreroll, the clutch B is disengaged, the clutch B engaged, and the press operated, which will rotate the compression-roll A and will take up any slack in said belt. The press is then in readiness to begin the formation of a new bale. Preferably, also, stops are provided to limit the approach of the movable compression-roll A to the stationary compression-roll A. As shown, lugs d are formed, one on each bearing-block a, which strike lugs d on the press-frame when the compression-roll A has attained desired proximity to the stationary roll A. This construct-ion will prevent cutting or other injury to the belt, which might result if said belt were subjected to a strong pressure between the unyielding compression-rolls and the small unyielding core-roll.

The belt or apron C may be made of any suitable material, as strong canvas, leather, rubber, or the like.
